Hi all,

After merging the pm tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

drivers/acpi/processor_idle.c: In function 'acpi_idle_enter_s2idle':
drivers/acpi/processor_idle.c:666:4: warning: 'return' with no value, in function returning non-void [-Wreturn-type]
  666 |    return;
      |    ^~~~~~
drivers/acpi/processor_idle.c:657:12: note: declared here
  657 | static int acpi_idle_enter_s2idle(struct cpuidle_device *dev,
      |            ^~~~~~~~~~~~~~~~~~~~~~
